To run the tomcat, which you installed(not the embedded one- and you need to run the manager portal of tomcat for auto deploy from maven

In eclipse ->

 Tomcat v7.0 Server at localhost.server  - take properties ->and click "switch location"

open it -> “server location” select “use Tomcat Installation(takes control of tomcat installation” 

now right click your spring project and run as “maven build “ -> tomcat7:redeploy will do the magic
